Combo contents
This bundle pairs an ASUS PRIME B860-PLUS motherboard with an Intel Core Ultra 9 285K processor and a tube of Shin-Etsu X-23-7868-2D thermal grease. It is intended for builders who want a matched CPU and board in one package. The LGA 1851 socket fits the supplied processor without a separate purchase.
Power delivery and thermal headroom
The board uses an 80A power-stage array across multiple phases plus a 6-layer PCB to keep voltage stable under load. The 285K CPU has a 125W base power rating with 36MB L3 and 40MB L2 cache for heavy multithreaded work. VRM heatsinks, an M.2 heatsink and dedicated pump and fan headers help move heat away from critical areas.
Bundled grease and software extras
Shin-Etsu X-23-7868-2D paste is included with a 6.2 W/m.k conductivity rating and 0.07 °C·cm²/W resistance, rated for a two-year replacement cycle. The board adds a pre-installed I/O shield, SafeSlot reinforcement, Q-LED diagnostic lights and ASUS DriverHub plus AURA SYNC addressable RGB control for easier setup and lighting coordination.

商品問答
Will the LGA 1851 socket on this PRIME B860-PLUS board accept my existing DDR5 memory kit?
The board uses an LGA 1851 socket with DDR5 support. Your current DDR5 modules will fit physically; enable XMP in the UEFI BIOS to run them at their rated speed.
How do I confirm the Intel Ultra 9 285K is running correctly after I assemble the combo?
The motherboard includes Q-LED troubleshooting lights that show CPU, memory, GPU and boot status. A steady white light means the processor has passed POST and is operating normally.
Does the combo box contain a CPU cooler or only the Shin-Etsu X-23-7868-2D thermal grease?
The package supplies the PRIME B860-PLUS motherboard, the Ultra 9 285K processor and a syringe of Shin-Etsu X-23-7868-2D grease. A separate cooler must be purchased.
